IMPROVEMENT IN CHURNS.

Specification forming part of LcttersPatent No. 55,996, dated July 3,1866.

To all whom it may concern.-

Be it known that-I7 JACOB BUYERS, of Orrville, Wayne county, State ofOhio, have invented a new and useful Improvement in Ohurns; and l dohereby declare the following description and accompanying drawing aresufficient to enable any person. skilled in the art or science to whichit most nearly appertains to make and use my said invention orimprovements without further invention or experiment.

rllhe nature of my invention and improve ments consists in the peculiaroperation of the dasher by means of motion being commnnicated therewithin an oblique or nearly rectilinear manner through an oblique arrangemenii of a shaft connecting in a peculiar manner with the horizontalarrangement ofthe dasher-shaft by-means of a curved plate and staples orhooks, the two shafts thus connected, when operating, producing anoblique rotary motion, which, as will be seen hereinafter, is simple andnovel in its form of construction and operation. The vessel or churn A,in which the two shafts thus arranged opcrates, is represented by aperspective view in the figure of the drawing, the greater or frontportion of it being broken out to give an interior view of theoperations of the same.

The churn is constructed of tin or other metal or material of a circularform and of a suitable size, having the lid or cover B thereonconstructed with an air-tube, a, for the admission of atmospheric airtherein, on the top of which tube there is a dish, a', to receive andcatch the drops of the Huid that maybe spattered up through the tubeduring the process of making the butter, the sloping sides of the dishreturning it to the mouth of the tube and thence into the churn again.

C is the shaft. It is arranged in an oblique or angular manner from thetop edge of the side of the vessel, and is let into a small groove orslot made from the top sufficiently to give `it a proper axial bearingtherein. The greater portion of this shaft is made of wood, having a rodproperly inserted therein or through at one end, which rod terminatesinto a crank form, with a handle, C', attached thereto to operate thesame. The shaft may be made entirely of metal, if deemed desirable. The

connection between this and the dasher-shaft D, which is arrangedhorizontally, as herein mentioned, is made by means of a curved plate,b, in one end of which two holes are'made, and a staple, b', passedthrough them andA driven into the ends of the dasher-shaft. In the otherend of this plate two more holes are likewise made and a staple passedthrough them and driven into the end of the oblique shaft, as in theother.

E is a ilexible and spring rod, one end of whichis attached alittlebelow theaxis ofthe rod ofthe oblique shaft by apivot, c. Theother end or part is bent at right angles to the other, so that whenplaced over the oblique shaftrod, it, being in the apex or corner of theangle thereof, is prevented from slipping out of its axis.

The dasher-shaft has its axial bearing on a rod, which is attached to asuitably-curved or other formed bridge-plate, d, constructed on amovable slide-plate, F. The rod extends from the bridge-plate throughthe center of the shaft and nearly the entire length thereof,sufficiently to give it the proper support in its revolution thereon. toslide in strips e e, attached to the sides of the churn, and extend fromthe top to the bottom of the same.

To keep the slide in place to prevent its slipping up in any way byreason of the operation of the dasher in its connection therewith, aflexible rod,f, is attached to a piu, f', near the top of the churn anda little beyondl the side of the strip. It is placed transversely acrossthe slide and over a pin, f", attached thereto, which rod is held by ahook or catch piece, g, secured to the side of the churn opposite to thepin, and while in this position secures the object above stated.

Operation: rlhe simple turning of the crankhandle imparts a horizontalrotary motion to the dasher from an oblique or nearly rectilinear one ofthe oblique shaft, as has been described, the lid having been removedand the cream or milk first poured into the churn, after which the lidis replaced again.

The advantages of this oblique horizontal arrangement of the two shaftsover those churns of a circular form in which straight shafts are useddiagonally arranged from one The slide-plate is made'i circular form ofchurn.

The axial points or bearings of a straight shaft, operatin gin themanner above described, are such thatthe shaft will work out of themwhen in operation, and thus prove a source of annoyance in replacing itagain, whereas by means of the flexible and spring rod, as arranged andapplied, the entire arrangement of the two shafts operates withfacility, unattended with any trouble as far as their axial points areconcerned.

When it is desired to remove the butter from the churn or clean the sameand its appurtenances tl1erein,it is done by releasing the flexible rodfrom the rod of the oblique shaft and releasing the other one from theslide-plate, and by takin g hold of the oblique shaft and the pin on theslide and pulling it up the Whole is entirely removed.y

llaving thus fully described my invention, what I claim therein as new,and desire to secure by Letters Patent, is-

1. The oblique shaft C, as arranged in its connection with thedaslJer-shaft l), by means of the curved plate b and staples b', to givean oblique or nearly rectilinear rotary motion when operating,substantially in the manner and for the purpose herein set forth.

2. yThe retention of the rod of the oblique shaft C in its axis by theflexible rod E and pivot c, as arranged and applied substantially in themanner and for the purpose as herein set forth.

3. The movable slide-plate F, strips ee, and bridge-plate d, in itsconnection with the dasher-shaft B, as arranged substantially in themanner and for the purpose as herein set forth.

4. The fiexible rod j', pin f', and catch g, for retaining` theslide-plate F when in' operation, substantially in the manner asarranged and for the purpose as herein set forth.

Y5. The dish a and air-tube ce, as arranged,

in combination with the lid B, substantially in tbe manner and for thepurpose as herein set forth.
